Wadi Qena is one of the largest dry valleys in the eastern desert of Egypt for the agricultural expansion. This study attempted to investigate the best agri-cultural land use of the middle part of this Wadi through its capability and suit-ability assessment based on its soil characteristics. So, forty-nine soil profiles were selected and digged to represent the soils of this area in February, 2017. One hundred and thirty six soil samples were collected from these profiles, to perform the physical and chemical analyses.
Sand, loamy sand and sandy loam textures were in this area. High variabil-ities were recorded in the soil salinity (ECe), soil alkalinity (ESP), total calcium carbonate content, soil pH, available N, P and K, soil depth which they varied from 0.83 to 187.6 dSm-1, from 7.41 to 17.8%, from 7.31 to 51.19%, from 7.70 to 8.81, from 2.3 to 88.8 mg kg-1, from 1.82 to 11.06 mg kg-1 and from 40 to 920 mg kg-1 and from 50 to >150 cm, respectively. Also, the hydraulic conductivity (HC), the field capacity (FC), the wilting point (WP) and available water capaci-ty (A.W.C) values vary from 2.92 to 38.00 cm/h with an average of 23.32 cm/h, 10.50 to 26.54 v/v % with an average value of 17.03 v/v %, 4.36 to 12.61 v/v % with an average of 7.63 v/v %, and from 4.96 to 18.13 v/v % with an average of 9.40 v/v %, respectively. |
